gaindakot on "[Theme: Hueman] Multi Column blog post in Home page"

I would like to get 4 column instead of two column posts in homepage. I saw there is an option for multiple column layout on the demo of hueman. I would appreciate any help regarding this.

I want homepage to be full width with 4 column.
